Functional
MRI study of pressure pain and its modulation using mental imagery
This study used functional magnetic resonance imaging (fMRI) to map areas
of activation in the brain due to pain, and to assess the changes in the
levels of activation when the perceived level of pain was modulated by
mental imagery.
